Abstract

Summary

The virulence of a strain of Trypanosoma gambiense was exalted to such an extent that it produced acute infection in mice (Mus musculus) which invariably terminated fatally within a week. Acute, always fatal Tr. gambiense infection in white mice was cured with adequate doses of nitrofurazone. A total dose of 50 mg./kg. body weight had only a suppressive effect. However, with an increase in total dosage from 150 mg./kg. to 450 mg./kg., divided into small doses and administered daily, cures were obtained in from 22 to 100 per cent of the cases. The curative results were approximately the same whether the drug was administered intraperitoneally or orally.
